Help me pick a project!
 

Hey yo everyone,

So I'm wracking my brain trying to figure out what the hell I'm going to do for a project for my car over this fall/winter/spring.

first off, the specs: 01 WS6, M6, 45k miles. Catback, lid, short-throw only mods right now. (Headers will be a FOR SURE addition no matter what path I go)

Goal: Anywhere in the 450-475 Hsp range. Money to spend: variable - Anywhere from $5000-$9000 all said and done. The other main goal is reliability. I have no problem replacing a few things here and there or spending a lil extra money to get the job done right, but I would like to avoid anything that is going to cause rough stress to the point I made need an engine rebuild in a "worst-case scenario". Car is daily driven, short distances, hasn't been raced yet, but I'd like to hit the track a handful of times after the project is done.

Options:

Heads/Cam: Kraest already enlightened me to the beauty for the Futral F13 high lift. I am pretty sold on that cam. In terms of heads, I was considering patriot IIs.... would AFR 225s be worth it for quality and power?? full valvetrain build up, all the timing/oil fixings as well. This should make good power, but relatively high-impact as well though I'm guessing.

Supercharger: Low-boost ATI, something in a #8 maybe? I love the appeal of a S/C, however I'm worried about wear on the engine. Some local guys have superchargers have stock LS1s and are fine with the right tuning and fuel setup..... But then there could be trans and rear end issues I'm assuming.

Nitrous: I actually have a OLD never used nitrous setup back at home. Would probably need some accessories and would have to make sure everything is in working order.... but i'm not too interested in this option. I would much rather have the jaw-dropping effect of hearing the "glug-glug" of the cam, or the "birdie under the hood" of the supercharger :cool:

Please feel free to educate me. I can be indecisive as hell, but I appreciate all your input and opinions.

Thanks as always.

I vote Procharger w/ 6~7psi of intercooled boost. H/C is nice, but you don't get the torque. Assuming you do the work yourself, you might be able to sneak in under your $9000 ceiling with a rear end and clutch too.

wow really? Clutch is like $900-$1200ish and Rear End is like $2500ish right? U really think I can get a whole project done with those things for under 9k?

With Procharger, I'll need injectors, fuel pump..... what else u think?

I thought the kit came with all of that? Clutch upgrade is less than $600 if you go LS2 flywheel and LS7 clutch. Got one in mine and it drives so smooth. :) Some creative searching and you might be able to find a used rear-end that just needs a refresh.

yea most the time those kits come with what you need, and the LS2 flywheel with LS7 clutch is your best bet. Rearends arent hard to find if you got the $$$

Interesting. Is that fuel equiptment that comes with the Procharger sufficient? I was thinking of getting the base kit and then picking my own pump and injectors.

You have to be careful when using the high-lift cams and aftermarket heads (especially if you have them decked) unless you want to fly-cut your pistons.

I wouldn't wipe my ass with an LS7 clutch. It just won't hold the added weight of an F-body + 450-475rwhp + multiple launches at the track. It's simply not aggressive enough, but should work nicely on a full bolt-on F-body or maybe a cam-only F-body (provided you don't neen to run it to 7000 rpm. :lol: )

The Ram Street Dual is a pretty awesome clutch (should hold around 900 lbs-ft) with soft engagement. The new Spec Twins (I know Spec has had a bad rap :lol: ) look VERY promising, but they are VERY pricey, however can handle upwards of 1500 lbs-ft!

If I had to choose between 3 clutches to handle 475-500+ rwhp on a project car, it would be these three:
1)Ram Street Dual
2)Textralia OZ700
3)Spec 4 or 5 Single Disc Unsprung units


After all is said and done, I'd rather Forced Induction than a heads/cam car anyday. You make more low-end torque and make more midrange than having to constantly zing a heads/cam car starting at 4000 RPM just to get it moving.

I believe that everything you need comes with the Procharger kit including the injectors, etc.

hey Kraest....what was the deal with the spec clutches?,I must have missed that.

Im asking because I have an older stage 3i in my LS1

I think you need to review his intentions. He's looking to keep this thing a smooth, daily driver that has some balls for when he wants to get up and go. It's not as much of a track car if he's only going "a handful of times" once it's together. The LS7 clutch should be fine for that. Had mine in for a short while now with no problems.

:shrug:

The sprung units explode.

Seriously:alert:

I was speaking to your clutch comment....

Like I said... It probably won't hold up to a good heads/cam package (470+ rwhp) for long behind a 3400-3500 lbs F-body.

Here's a quote from Ranger, who holds the stock C5 Z06 and stock C6 Z06 1/4 mile records:

Take it for what it's worth.
:shrug:

There are much better options for the same amount of money.

You have a PM, Rick.

My buddy had a procharger on his 02 Z28 and was pushing 480 HP, probably had some bolt-ons, but I don't remember, this was 3 yrs ago. He worked for procharger here and got a HELLA deal (under 2K for everything), but you could do the same for WELL under your budget and have some left over for clutch and rear end (or whatever), especially if yo7u find a kit used. This would be the way I'd go if it were my car.
